Ugandans decides on Thursday after one of the violent election campaigns, as the pop star politician Bobi Wine tries to unseat Museveni from his 34-year rule.

Wine is one of nine opposition challengers, and has won huge support.

Many observers see the challenge to Museveni, who is 76, Ruling for 38 years, as emblematic of a continent-wide generational struggle between ageing leaders who refuse to relinquish power and younger voters mobilising against them.

More than 55 people died in November after Wine was officially confirmed as a candidate, and he has been detained and prevented from campaigning.

On Wednesday, the US and EU said they would not observe the elections, after several officials were denied accreditation.

Ugandan authorities have, in an unprecedented move, shut down the internet in the country hours to the Jan.14 polls, a move that has been widely criticized.
